watershed2: Alternative watershed algorithm

In pliman: Tools for Plant Image Analysis

Alternative watershed algorithm

Description

This is a basic watershed algorithm that can be used as a faster alternative to EBImage::watershed(). I strongly suggest using this only with round objects, since it doesn't consider both 'extension' and 'tolerance' arguments of EBImage::watershed().

Usage

watershed2(binary, dist_thresh = 0.75, plot = TRUE)

Arguments

binary	A binary image
dist_thresh	The distance threshold to create the
plot	If TRUE (default) plots the labeled objects

Value

The labelled version of binary.

Examples

library(pliman)
img <- image_pliman("soybean_touch.jpg")
binary <- image_binary(img, "B")[[1]]
wts <- watershed2(binary)
range(wts)
